vIIBLE CARD INDEX Filed Mareh 25', '1927 ATTORNEY Patented Jan. 28, 1930 PATENT OFFICE LUIGI LOMBARDINI, OF TURI, ITALY VISIBLE-CARD INDEX Application filed March 25, 1927, Serial No. 178,359, and in Italy April 12, 1926.

The invention relates to improvements in card indexes and particularly to that class in which the cards are held on a support so as to.v overlap one another.

The object-of the invention is to provide index cards so that they can be readily apends of which extend between the members 13 plied to and removed from the support. The invention consists of a card having front and rear portions provided with acentral passage between them, one of the portions having an opening and tongues to facilitate the entrance of a support into said opening and retain the supportin said opening and the other portion having a tongue adapted to enter the passage o a previously applied card, so that the cards can be applied to the support one overlapping the other.

In the drawing;

Figure 1 is a det Figure 2 is a side view of bot parts of the card together with a portion of a support for the card with which it isengaged,

Figure 3 is a transverse section oFigure 2, and

Figures 4 and 5 are an elevation and a cross section respectively of a modified form of card.

Fig6 is a view of two of the cards of the first form in nested relation.

Like reference characters designate corresponding parts in all of the views.

The card is composed of two parts ll'and 11. The part 11 is provided with the central tongue 12 projecting from its upper edge and with a Hap at each side of the tongue, said iaps forming two members 13 and 13. The other party 11 of the card consists of a central portion formed with a horizontal slot 20 spaced from the top edge a distance equal to the overlap of the cards, from one end of which slot the oblique curved slot 20 extends out through the lower end of said part and forms the downwardly projecting tongues 17` and 18. The part 11 ofthe card has at its upper end band-like members 15 and 16, th'e lemployed for securing the said parts together.

ail view of a art of a card,

By thus constructing the tongues, a support can be readily inserted in the slot 20 and when so inserted a portion of each tongue will overlie the support and thus retain the support in the slot and the card on the support.

As shown in the drawing the support is a bar or rod 1, but a tape, cord or other iiexible support may be employed. To apply the card to the bar 1 a card is brought into engagement with the bar and said bar or card is moved laterally to cause the bar to enter the oblique slot 20 and pass under one of the tongues 17 or 18 and enter the slot v20, and then by a reverse movement of the bar or card, the bar will pass under the other tongue and the. card will be held on said bar. To remove the card the bar or card is manipulated to cause the bar to pass out through the slot 20. When another card is to be applied to the bar 1, the card is applied to the bar below the first card in the same mannery as ,the l'irst card and then it is slid upward on 'the bar under the tongues 17 and 18 of the irst card, when its tongue 12 will pass into the passage between the parts of the cards. It-will thus be seen that the cards can he readily and quickly appliedand that when a number of cards are applied they will be nested or overlap one another. In the moditication ot Figures 4 and 57 the construction of the card is similar to that shown in the, other igures, except that the parts of the card are secured together a little diiierently. In these views the members 13a are provided with a slot 22 of a length slightly greater than the width of the band-like members 15 and 16. Thus, it will be seen that the members 13u .provide tabs 23 and 24. The band-like members 15 and 16 of the parts 11 are disposed and 16. Thebands 15 and 16 may be secured -to the tabs l23 and 24 by staples 25.

What I claim is 1. A visible card index comprising a guide and a card formed of two interconnected parts and adapted to be inserted on the guide with onepart beneath the guide and the other part partly underlying and partly overlying. said guide, v

2. In a card index, a card formed of two parts secured together to form a central passage between them, one part having a tongue at its upper edge adapted to enter the passage of an Iadjacent card and the other part having tw'o tongues, and an openingadapted to receive a sup ort and providing rtions adapted to overlie the support an old the support in the opening.

3. In a-card index, a card formed of two parts secured together to form a passage between them, one part bein provided with a tongue at its upper edge, a a ted to enter the passage of the adjacent car the other part aving a horizontal slot spaced from its upper edge and a curved slot leading from one end of the first-mentioned slot out through the lower end of the part and forming two tongues, and said last-named part having oppositely rojecting band-like members at its upper e ge.

4. In a card index Provided with a guide rod, a. eard formed o two parts secured together to form a assage between them, one part being rovidled at its vupper edge with a. ton e a apted to be nested in the correspon 'ng passage of an adjacent card, the other part having a horizontal slot adjacent f its upper ed e, said slot bein of substantially the same ength as the wi th of the guide rod, and an obli ue curved slot leadin from one end of said rst-named slot out t rough the lower end of the part and forming two tongues, said tongues being defined in part by rounded edges leading from the edges of said oblique slot.

In testimony whereof, I have aixed my signature.

LUIGI LOMBARDINI.
